IMPROVEMENT IN INJECTORS FOR STEAIVF-BQILER S-i Specification forming part. of. Lett'ersPat'ent No. 222,497, dated December 9,1879; applicationfiled- May 15, 1879.

To all whom it may concern:

Be it known that I, LOVREN EDWIN HOGUE, of Sandy Lake, in the county of Mercer and State of Pennsylvania, have invented a new and useful Improvement in Injectors for Steam- Boilers, of which the following is a specification.

Figure 1 is a longitudinal section of my improved injector. Fig. 2 is a detail cross-section of the same, taken through the line or m, Fig. 1. Fig. 3 is a detail cross-section of the same, taken through the line y y, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved injector in which the lifting and forcing tubes are so constructed and arranged with regard to each other that the pressuremay range from forty to one. hundred and fifty pounds without requiring any change in their adjustment, the said constr ction and arrangement enabling the quantity of water to be so graded that three or more difierent quantities of Water may be injected into the boiler.

The invention consists-in the combination of three or more sets of upper tubes, the two or more sets of lower tubes, the steam-cham-. bers, the water-chambers, the valves, and the stop-cocks with each other, as hereinafter fully described.

A represents the steam-chamber, into which the steam is introduced through a pipe, a, leading to the boiler, and from which the steam passes through the tubes B, placed in pipe 0, and passes through chamber D into tubes E, the cavity of which is larger than the jet of steam, the velocity of the steam carrying the air out of chamber D through the overflow, thereby causing a vacuum, which brings the water through pipe d into chamber D, said pipe 01 leading to a well, cistern, or other ater-supply. The water is held in chamber D by the condensation of steam in tubes E, and forces the water through tubes E into the water chamber or reservoir F. The tubes E have their upper ends recessed or made cup-shaped, and are arranged with their said upper ends directly below and close to the lower ends of the tubes B. p

The tubes E are placed in passages or pipes G, leading from the upper water-chamber, D, to the lower water-chamber, F.

H are the lower steam-chambers, into which steam is introduced from the boiler to the pipes h, and from which it passes through the tubes I into the water-chamber F, where it is condensed by the water in said chamber F, the condensation thus formed, together with the action of the steam, forcing the water from the chamber F through the tubes J into the boiler. The tubes J are placed in pipes or passagesm, leading from the lower water-chamber, F, and connected at their lower ends with pipe N, leading to the boiler. The tubes'J have their upper ends recessed or cup=shaped, and are arranged with their upper ends directly beneath and close to the lower ends of the tubes I.

Three sets of the tubes B E and two sets of the tubes I J are represented in the drawings; but the number may be increased, if desired. Two of the tubes B, or'all of them but one, are provided with screw-valves K, so that one or more of the said tubes, or all of them but one, may be closed, as desired.

Two of the passages or pipes G, or all of them but one, are provided with stop-cocks L, to allow one or more of them, or all of them but one, to be closed, so as to prevent the water forced through tubes E from returning back to chamber D.

The three or more steam-pipes a h It may be all connected with a single pipe leading to the boiler, and should be provided with valves or stop-cocks to shut oif steam from tubes not in use.

The pipes N may be connected with a sin gle pipe leading to the boiler, and should be provided with valves or stop-cocks to pre vent the water ffom returning through the tubes J to chamber F.

The lower water-chamber, F, is provided with an overflow-pipe, f, which is only used for the tubes I J is made of sucha size as to discharge so much water as will be admitted through two sets of the tubes B E. The cavity of both sets of tubes I J is made of such size as to Ellis) all the Water lifted by three sets of tubes With this construction, by adjusting the valves and stop-cocks, three diiferent quantities of water may be injected into the boiler, and by increasing the number of sets of the tubes B E and I J any desired number of changes of quantity may be made.

Having thus described myinvention, I claim as new and desire to secure by Letters Patcut- The combination of three or more sets of grading-tubes B E, the two or more sets of tubes I J, the steam-chambers A H, the Water'chambers D F, the valves K, and the stopcocks L with each other, substantially as herein shown and described.

LOVREN EDWIN HOGUE.
